摘要

为探讨安装极低屈服点软钢阻尼器的钢框架结构抗震性能,对地震观测用的三层钢框架结构实施了拟动力试验,输入的地震波为该结构历年的地震观测记录.本次拟动力试验选用了4个地震波记录,分安装阻尼器和未安装阻尼器两种情况共计进行了8次试验.试验结果表明,软钢阻尼器可以有效地减小结构的地震反应,结构地震反应的试验结果和观测结果具有良好的一致性.
An experimental study on seismic behavior of steel frame attached with hysteretic dampers using ultra-low-yield-point steel is presented. The pseudo-dynamic tests are based on a scaled 3-story steel frame model that was constructed for earthquake monitoring. The pseudo-dynamic tests using various earthquake inputs, which were recorded by the sensor set in the site. The eight tests with and without hysteretic dampers using four earthquake records. The case studies considered in offer great insight into the significant effect of hysteretic dampers. The comparison of response history results with monitoring and pseudo-dynamic tests agree with each other fairly well.
